Shopping for Canon ImageFORCE C521F Toner Cartridges

The Canon imageFORCE C521F is a full-color laser multifunction printer designed for busy offices needing fast output and flexible media handling. It delivers up to 55 pages per minute (letter size) and supports print resolution up to 600 × 600 dpi in standard mode — or an effective 1,200 × 600 dpi equivalence in lower-speed quality mode. The printer handles a wide range of paper weights (from about 60 g/m² up to 163 g/m² in the cassette, up to 216 g/m² via the multipurpose tray) and supports media sizes up to 8.5″ × 14″ (with both cassette and multipurpose tray). Paper capacity starts with a 640-sheet cassette (at lighter paper weight) or 550-sheet cassette (at standard weight), plus a 100-sheet bypass tray; output capacity is up to 400 sheets or ~65.2 mm stack height. First-copy output (color) takes about 5.4 seconds for A4/letter originals; continuous copy speed aligns with print speed (approx. 52 sheets/minute for A4 plain paper). Scanning and duplex functionality are supported (single-pass duplex automatic document feeder), and the unit is built for reliability and high throughput, with scalable paper supply (up to 2,300 sheets with optional additional cassettes) making it a strong fit for medium-to-large workgroups or departments.
